1. I have an Aldi Cordless Hedge Trimmer, powered by a 20 V Lithium-Ion battery. It is manifestly under-powered - jams frequently - and their tec support cannot offer any advice ("At that price what do you expect?"!!)
I see however that you can run the machine with an optional 40 V battery. Question: Would this improve the power (torque) of the motor, or as I was told would it do no more than extend the interval between recharges?
2. I have a 12 v battery in the car which is "borderline" age-wise. I can charge it up to over 12 v but it is not very good at holding the charge. I have also a simple DIY multi-meter. When I test one with the other the reading fluctuates and I have to guess what the underlying value is. Is this likely to be an indication of the state of the battery, or of the multi-meter which is probably in the same age bracket? Can one get multi-meters with a "stabilised" read-out, and is it worth simple DIY people like me investing in one just for occasional use?
Advice on either (or both!) topics much appreciated.
